Justin Bieber‘s mom has some messages to share following her son’s marriage ceremony. One day after Bieber, 24, and Hailey Baldwin, 21, secretly tied the knot on Thursday, Pattie Mallette, 43, tweeted, “Love is unconditional.”

On Sunday, she wrote, “Haters gonna hate. #LoveWins.”

Bieber and Baldwin were legally married at a courthouse in New York City, PEOPLE confirmed. “They went ahead and did it without listening to anyone,” a source told PEOPLE

The model said on Friday that she does not consider herself hitched. She wrote in a now-deleted tweet, “I understand where the speculation is coming from, but I’m not married yet!”

A pal of the couple explained to PEOPLE that Baldwin “feels a civil ceremony and their ‘real’ wedding are two separate things.

A religious source spoke to the family and confirmed to PEOPLE that they were legally married at the courthouse, but are going to have a religious ceremony and celebration with family and friends soon. “They’re going to have a big blowout, in front of God and everyone they love,” the religious source tells PEOPLE.

“Since they began dating, Justin has been 100 percent committed,” an insider told PEOPLE. “They’re young and in love and feel confident about their relationship.”

After Bieber popped the question to Baldwin in July, Mallette wrote on Twitter, “Love Love Love Love Love Love Love.”

In 2015, Bieber told Billboard that his relationship with his mother was “pretty nonexisting” for about two years.

“I was distant because I was ashamed,” he said. “I never wanted my mom to be disappointed in me and I knew she was. We spent some time not talking, so it takes time to rebuild that trust … it’s hard, but getting better. She’s an amazing woman and I love her.”

Speaking with PEOPLE about her parenting style in 2013, Mallette said, “When your kids hit a certain age your parenting style changes and it is hard letting go. His life was my life and now I’ve had to let him go a little bit and let him be independent. It is hard to not be able to control everything that your adult child does.”
